A 220 story building in Neo-Valentis owned by the criminal organization CIONIDE is one of three bases working on the development of a high-tech AI entity named ''Prime Mover Anima'' being custom made to over-ride every computer system in the world.

AI projects like this has been illegal and stopped for centuries due to the fear of entities breaking free and posing extinction threats on humanity.

KEON must attack the fortified building which is built with bulletproof metal, which is packed with turrets, lasers, drones and other advanced military power. The only way to get in is from the top, and flying in with vehicles is not an option due to the anti air weaponry installed around the entire area. He can only equip an advanced shield, run up the High-Rise, destroy the weaponry and get in from the top, plant a bomb, jump off and hope he'll survive.

Unit 187 will do their best to distract the enemies, attack from afar and give him as much support as possible. This is classified as an Impossible Mission. But KEON goes out of his way to prove everyone wrong and his pumped as hell to get this done.
